In 1865, the Ohio General Assembly designated a room in the rotunda of the Statehouse as a display area for "the old, war-worn colors, and other relics, received from our brave soldiers." Unfortunately, the years of exposure to sunlight and dust have taken their toll on the battle flags. In 1989, the Ohio Historical Society placed the flags in storage to preserve what remained of the colors. Although the Ohio Historical Society and Ohio Historical Foundation have begun a fundraising campaign to preserve the flags, it will never be possible to physically display all the flags in one location again. The Online Relic Room is the Ohio Historical Society's virtual display area for the military symbols that meant so much to Ohio's veterans and families.

In the Online Relic Room, there is an exhibit gallery for each war and a search function to find specific flags.
